Abstract In this study, flexural behaviour of the Ferrocement panels of size 500 mm x 500 mm x 50 mm with partial replacement of ceramic powder under monotonic loading is observed. All the Ferrocement panels were casted with cement mortar of mix proportion 1:4 with w/c ratio of 0.45 and all the specimens were casted with single layer of galvanized welded wire mesh of 2mm diameter with mesh opening of 12.5 mm x 12.5 mm. The ceramic powder is administered at various percentage replacement of cement by weight and the adopted variations are 0%, 5%, 10% and 15%. Compressive strength of the mortar mix for all the different ratios of ceramic powder was carried out and the results were discussed. It can be concluded that the Panel with 10% replacement of ceramic powder offers appreciable results than the other panels.

Recycled Fibres

In the present study the steel fibres coming from the end-of-life tires were applied as a reinforcement of self-compacting concrete. The influence of the recycled fibres and their mixture with glass or polypropylene fibres (hybrid mixes) on the flexural behaviour of SCC was tested. The research revealed that the dosage of 1.5% of recycled fibres is highly effective in the SCC matrix. The values of the residual flexural tensile strengths obtained in the tests classified the R-SCC to be used as a partial replacement of the conventional reinforcement. The addition of other types of fibres to R-SCC caused the further enhancement of flexural parameters with no negative effect on the distribution of the fibres in the mix.

Structural Failures

In modern days for structures in coastal areas it has been observed that the premature structural failures are occurs due to corrosion of the reinforcements of the designed structural member. The corrosion causes the structural damage which in turn leads to reduction in the bearing capacity of the concerned structural members. The aim of this study was to study the effect of partial replacement of fly ash to minimize the corrosion effect. Beams were designed and corroded by using artificial method known accelerated corrosion method. The beams were then tested for flexural and bond strength. Also the weight loss of the reinforced bars was been determined using electrical resistivity method. The fly ash will replace by 10% and 15%.The strength will calculate at varying percentage of corrosion at 10% and 15%. Beams will cast at M25 grade concrete. The flexural strength will test by using UTM and the bond strength will calculate using pullout test.
